The
pp UBR
virtual circuits between A500 ports
A1.1
(PPN) and
Self
(A500) and between
A1.2
(EPN) and
Self
(A500) are ATM signaling
channels between the port network and the A500.
■
They are used to request connection setups and releases to other end
points such as another port network.
■
These are established by each TN230X when it comes up, independent of
the Avaya MultiVantage Software Call Processing.
■
Other UBR virtual circuits may exist between A500 ports that are not
associated with Avaya Definity Server CSI port networks and may be
signaling channels for other applications (for example, data network traffic).
